yup. Running them in my Rockwells. Its the same locker as the 14 bolt with different side gears.
Ive beat the snot out of them and have been very impressed. Cosmetically they look as good or better than a Detroit and I think they function better.
I wouldnt hesitate to buy them again.....especially for the price. They are a great product!

??? More reliable than detroit WOW I haven't had a problem with the bigger detroits 44,60 9" etc. The only detroit issues I can remember was due to exploding shafts.
MY 2 cents
MY 2 cents
I believe Shawn had a D60 Detroit go bad on him after a snapped axle or u-joint. That was a while back too.
I've also had good luck with my rear detroit. Solid unit, never gave me any problems.

I havent busted a shaft with my Grizzlys but I did several with my Detroits....Never had a issue with it. Their design is basically the same so Im guessing they are saying no issues due to better materials.
However.....My First Detroit blew to bits on the first trail I took it on. I was PISSED!

It's Grizzly, no 'e'
Grizzly is about 10% stronger than a Detroit
Grizzly will not fail if a shaft, hub, u joint, etc. breaks
Grizzly is less expensive than a Detroit
Grizzly has a 1 year warranty
Grizzly is approved to use in NASCAR events
Grizzly will unlock/lock faster than a Detroit and is actually quiter because of it
I hear of 14 bolt Detroit's blowing up all the time. I've switched some over to a Grizzly; they like them better and haven't busted them yet. Like Cheston says, it's the same basic design that is in the Rockwell. Actually (technically) they came up with the 14 bolt design and then used it for the Rockwell and AAM 11.5" units.
To date there hasn't been ONE Grizzly (or Spartan) failure.
Dana 60 Grizzly's should be ready in a few weeks
Plus, if you buy a Grizzly by Oct 31st, you also get a $2,000 collateral damage warranty. Meaning that should the locker fail and say destroy anything else in the process, they will pay up to $2,000 to repair it (labor included) PLUS warrranty out the Grizzly.
Drop me a PM if you want a price quote!
Here's a picture of what the side drivers look like. This is typically the failure point.

Randy flew me over to tour their facilities in July. While doing so, he showed me the drawings and sample pieces of the Grizzly and what goes into assembly and quality control of them (and the entire Yukon line). Trust me, there is a big difference. :greg: And honestly, the differences are no brainers.
I'm not sure what I was impressed with more; the Yukon line, the quality control steps or how intelligent Randy is. Apparently he's some kind of rocket scientist
While showing me around, he was explaining what his employees were doing. If they had a drawing up on the screen, he knew what the drawing was of. Going through the QC labs, he knew how the machines worked and the tolerances of the parts they were looking for. Not only is he the CEO/founder, but I'm pretty confident that if an employee was missing, he could easily fill in.Rusted should look into doing a tour with Randy. Not sure about photos? Because some of it is behind locked doors...But very impressive.

It was!
I just got an email from Randy's with their new QC equipment/rooms. So apparently it's not top secret enough that I can't share
http://www.ringpinion.com/Quality.aspx
The two pictures on this page are just of the one room, roughly 8x16. The one big machine in the first picture is a big marble slab with a gantry type deal. They then bolt the part to the table, and this gantry probes the entire part and compares the part to the drawing, down to .0002". Figure 1.4 shows the points they are verifying. Any guess to what part it is?
Both rooms are temp/humidi controlled. Before a part is tested, the part is brought into the room to sit for 24? (might have been 36?) hours and normalize.
Then there is the article
http://www.ringpinion.com/Content/Quality_Control_Tech_Report.pdf
Figure 2.3 is a tool that measures how 'rough' the face of the gear is. Randy's designs their own gears, rather than using OEM or other manufactures designs. This enables them to control how their gears are made - they now have an industry first, a quiet gear set for the Chrysler 9.25! Not even Chrysler has a quiet gear set
If the surface is too rough, then the gear is reboxed as a USA Standard gear and will not make it into a Yukon box. This is in their other room, which is about 20x25?Figure 3.3 is where the Spectrometer checks the material. It comes back with how much of each ingredient is in the material. The computer then has a database and by this, the computer then spits out what material it actually is. You can see all of the numbers blurred out to the right and to the left each 'ingredient'
The door behind figure 7.1 is their larger QC lab.
Figure 7.5 is one of their D44 shafts in purple and a competitors in pink. The machine actually spits out this print out, too. Randy focuses on strength, rather than deflection. You can see this very clearly in the chart. The competitors shaft almost completely twisted before it broke, the whole time the tire probably wasn't even turning. Some deflection is necessary to absorb shock loads. But Randy figures it's more important to maintain the shaft when you are bound up, so you can pull yourself out of it before busting the shaft.
The one shaft we tested while I was there busted at the ears and Randy was very shocked to see it break there. That shaft was then analyzed to figure out why it broke there and not down at the splines like normally.
Notice their standard 4340 shaft will go beyond 6,000 ftlbs of torque before failure
Spicer 760 joint is rated at 5400 ftlbs.Recognize the part in Figure 9.1? That's a Grizzly driver being tested. Not sure what I can say here and not share a trade secret...
Anyway, very cool indeed!!!

lol I just saw that PM! Tomorrow night I think it was...
It was a very interesting tour and I highly encourage you to check it out. Randy's/Yukon isn't even really the same company they were 2 years ago. So much has changed in such a short time....

Anyone catch the Yukon tour on PirateTV tonight? The import Yukon 4340 shaft was stronger than Superior's DOMESTIC shaft at 5700 ftlbs of torque. Superiors import and the Ten Factory shaft (made out of the same plant, using the same forgings) went 5200 ftlbs. The Domestic Yukon went to 6100 ftlbs of torque, this is their new hardcore line.
That axle breaking machine is crazy loud! The video doesn't do it justice. You hear Camo? said it made him jump. It does. Even expecting it. It's hard to describe it. Kind of like having your ear at the barrell of a .45 when it goes off, except for it doesn't ring afterwards.
The room they pushed the machine into at the end is the larger QC lab.
That wall of shafts stuffed through the holes is thier one offs. They try to keep at least 1 of everything in stock, even if they only sell one every 2 years. Randy strives to be the king of the hard to find part.
I really can't wait to see the Zip Locker for the Dana 60. I've known about the 'trick stuff' for over a year now and I just can't wait to see how it works out!!
Notice in the video they talked about the new Zip Locker case? Remember the video of ARB testing the Zip Locker prototype and it failing? You think it will fail now? The cases are no longer made in India..... Better forgings, tighter quality control, more money, better product.

I posted the results to their destructive axle test:
